A comparison of the retinal image quality and intraocular scattering between the two groups at 3 years postoperatively

Parameters	ICL group	LRS group
OSI	1.28 ± 0.60 (0.23–2.65)	1.79 ± 0.94 (0.73–3.95)
MTFcutoff (cpd)	34.70 ± 9.10 (19.89–51.87)	27.48 ± 8.44 (8.86–41.56)
SR	0.18 ± 0.55 (0.11–0.29)	0.16 ± 0.04 (0.07–0.23)
OV100%	1.15 ± 0.30 (0.67–1.70)	0.90 ± 0.26 (0.35–1.37)
OV20%	0.79 ± 0.27 (0.40–1.40)	0.63 ± 0.18 (0.25–0.97)
OV9%	0.44 ± 0.17 (0.20–0.80)	0.37 ± 0.12 (0.15–0.57)

cpd = cycles per degree, ICL = implantable collamer lens, LRS = laser refractive surgery, MTF cut‐off = modulation transfer function cut‐off frequency, OSI = objective scatter index, OV = optical quality analysis system values, SR = Strehl ratio in two dimensions.

The results are expressed as mean ± SD (range).
